BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 230,423, dated July l27', 1880, Application filed May 1,1880` (Model.)

To all lwhom it may concern ,y

Be it known that I, JOHN F.KING, a citizen of the United States, residing at Washington city, in the District of Columbia, have invented certain new and useful Improvements in Bottle- Stoppcrs and mechanism for operating them; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyin g drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

The object of my invention is to provide a cheap, simple, and effective mechanism for fastening a stopper to a bottle, whereby such stopper may be readily operated by means of the finger or thumb of the hand grasping the bottle, while the other hand is free to grasp the tumbler or vessel into which the contents of the bottle are to be discharged, and whereby the stopper may be permanently fastened to the neck of the bottle to prevent loss, as more fully hereinafter specied. These objects I attain by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of my improved stopper-operating mechanism secured to the neck of a bottle; Fig. 2, a vertical section through the neck of the bottle and stopper mechanism, showing the mouth of the bottle closed; and Fig. 3, a side elevation of the same, showing the bottle open.

The neck of the bottle A is formed with an upper and a lower annular depression, a a', into which tie-wires b b are fitted, which also tit into grooves in the upper and lower edges of a metal plate B, which is thereby closely held against the side of the neck of the bott-le.

The plate B hasa pintle or pivot-pin,B, that projects from it and passes freely through an elongated slot, c, in the end of the finger-plate C, the upper end of which is bent over to press upon the upper end of the stopper, and is in this instance provided with a downwardly-projecting hub or boss, c', that lits into the upper end of a rubber packing, hereinafter described, and partly enters the mouth of the bottle.

The pintle or pivot-pin B projects beyond the plate C, and passes through one end of a :and turned in, so that the projecting edge of the plate B, and the cam, D', so that the cam Dl of the lever will rest against the outer face ofthe lower end of the linger-plate C and completely cover its slotted portion. The outer edge of the cam D bears against the shoulders c2 c3 upon the side of the linger-plate, so that when the cam D' is turned upon the pin B the finger-plate C will be raised or lowered, the pin B passing through the slot o of the finger-plate, which will admit of the movement of the cam-lever.

The ends of the wires b b', which hold the plate B to the neck of the bottle, are twisted they will be covered'by sharp points of the wire will not be exposed to cut the hands.

The rubber stopper packing E is of peculiar shape, and is provided with a recess, e, in its upper end to receive the plug or stopper c of the linger-plate C. The rubber stopper E is also provided with an annular rim or flanged portion, e2, which rests upon the upper edge of the mouth of the bottle and is closely pressed against it by the cap c4 of the linger-plate. A perfectly airtight stopper is thus obtained, and the pressure of the gas within the bottle will exert itself upon the dished face of the lower end of the stopper and exert itself to force the lower outer edge of the stopper more closely against the in ner surface of the neck of the bottle.

The stopper is, by means of the abovedescribed mechanism, at all times under complete control, so that it may be opened slowly, or only partially opened, to let off an excess of gas when the bottle is overcharged, and thus prevent the waste of its contents when poured out. When the lever is down the bottle is closed. When it is forced to one side the pressure of the gas within the bottle will completely raise the stopper, so that the stopper and its connections will either fall to one side or may, with a slight movement of the hand or fingers, be thrown to one side of the mouthof the bottle, be poured out without obstruction.

I claim as my invention and desire to secure by Letters Patent- I. The combination, with the neck of a bottle and an arm provided with a suitable stopper and arranged to slidevertically and swing so that its contents may IOO laterally on :t suitable bearing at one side of the bottle, of a pivoted rotating cam-lever arranged to operate sai d arm in its Vertical movements to both open and close the stopper, substantally as described.

2. The combination, with the longitudinally sliding` and swinging ngerplate C, provided at its upper end with a stopper, and having two shoulders on its vertical portion, of a pivoted cam, arranged to play between said. shoulders, for operating said finger'plate, substantially as described.

3. The combination, with the neck of the bottle, of the pivot-plate B, linger-plate C, provided with a stopper upon its upper end and 15 by means ofthe cam-lever, substantially as de- 2o scribed.

In testimony whereof I :Lfx my slguature in presence of two witnesses.

JOHN F. KING.
